First, you need to distinguish between a crash and a simple shutdown
of the program. A crash is handled by the operating system, not by
the program (e.g., UNIX core dumps, Windows95 reports that the program
has performed an illegal operation). In this case, the program simply
shuts itself down because it has determined that it has encountered
invalid or undesirable data.

exit() exits the program. Which is probably why it's called exit()...

No it isn't. That's not stock code, and it's wrong. The player isn't
even in a room yet, so how can they be removed from it?

It's the same as,
load_result = Crash_load(d->character);
if (load_result)
-> if (GET_LEVEL(d->character) < LVL_IMMORT && !PLR_FLAGGED(d->character,
->PLR_FROZEN)) {
-> char_from_room(d->character);
-> char_to_room(d->character, load_room);

This is not stock code, and it is where you are having a problem.

What load_result was doesn't make a difference, because it gets

I suggest a book on ANSI C.
ObProgrammerHumor: Whoever said syllogisms couldn't be humorous?
(actually, this isn't actually a syllogism in the strictess sense of
word, but whatever),
Fact: Development engineers (e.g., programmers) on break talk
about football.
Fact: Senior engineers on break talk about tennis.
Fact: Executives talk about golf.
Conclusion: The higher you go on the corporate ladder, the smaller
your balls are.
Hm, perhaps that proves syllogisms aren't funny.
